Disclosure of Invention

The technical problem to be solved by the embodiments of the present application is to provide a mobile terminal, where a touch screen of the mobile terminal can be repeatedly used after being detached.

The embodiment of the application also provides an assembling method of the mobile terminal.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an embodiment of the present application provides a mobile terminal, which includes a housing, a cover plate, and an elastic member. The shell is provided with an accommodating cavity, and an installation groove surrounding the accommodating cavity is formed in the cavity wall of the accommodating cavity. The elastic piece is contained in the mounting groove. The edge of the cover plate extends into the mounting groove and extrudes the elastic piece. Fixing the cover plate into the accommodating cavity of the shell through elastic deformation of the elastic piece.

The mobile terminal further comprises a touch screen, and the touch screen is contained in the containing cavity and fixedly connected with the cover plate.

In this embodiment, the elastic member of the mobile terminal is elastically deformed to generate an elastic force for fixing the cover plate, so that the cover plate is fixed to the housing, and the touch screen fixed to the cover plate is also fixed to the housing. Dismantle the apron with during the touch-sensitive screen, make through great effort the casing takes place deformation, the produced fixed of elastic component the elasticity of apron weakens or disappears, the edge of apron leaves the mounting groove, the apron with the touch-sensitive screen leaves the casing to accomplish the dismantlement. Because the casing passes through the produced elasticity chucking of elastic component is fixed the apron, the apron with realize dismantling the connection between the elastic component, the apron with do not have adhesive force between the elastic component, consequently dismantle the apron with the degree of difficulty of touch-sensitive screen is less, can not harm the touch-sensitive screen during the dismantlement for touch-sensitive screen after the dismantlement can used repeatedly, thereby avoids causing huge material waste in mobile terminal's production and the maintenance process, practices thrift the cost.

Because the elastic piece is extruded between the mounting groove and the cover plate, no gap exists between the shell and the cover plate, and the mobile terminal can realize water resistance and dust resistance. Because the cover plate is connected with the shell through the elastic piece in the direction perpendicular to the light emitting direction of the touch screen, namely in the direction of the display plane of the cover plate, the cover plate is in hard-soft-hard connection with the shell, when the mobile terminal is collided, the elastic piece can play a buffering role, and therefore the risk of the cover plate cracking is reduced. Because the bonding structure is cancelled between the cover plate and the shell, the shell does not need to be provided with a bonding surface for bonding the cover plate, and the width of the black edge of the mobile terminal can be reduced.

It can be understood that, in the vertical direction of touch-sensitive screen light-emitting direction, the edge of apron with the mounting groove compresses tightly jointly the elastic component, consequently the shape of mounting groove reaches the shape of elastic component with the shape looks adaptation of the edge of apron makes the mounting groove the elastic component reaches the cooperation between the apron is inseparabler. For example, in a direction perpendicular to the light emitting direction of the touch screen, the edge of the cover plate is substantially rectangular, the mounting groove is rectangular, and the elastic member is also substantially rectangular.

In one embodiment, the elastic member is made of a material having elasticity and no adhesive force. For example, the elastic member is made of an elastic resin material or a silicone material. At this time, the elastic piece can generate the elastic force for fixing the cover plate, and meanwhile, no adhesive force is generated between the elastic piece and the cover plate, so that the cover plate and the touch screen can be conveniently mounted and dismounted.

In one embodiment, the resilient member is of unitary construction with the housing. The elastic piece is fixed to the groove wall of the mounting groove and is in non-detachable connection with the groove wall, so that the elastic piece does not displace in the mounting and dismounting processes of the cover plate, and the assembling efficiency and reliability of the mobile terminal are improved.

Optionally, the elastic member is directly formed on a groove wall of the mounting groove in an injection molding manner, so that an integrated structure of the elastic member and the shell is realized, and the connection is firm.

Or the elastic part is bonded on the groove wall of the mounting groove through back glue, so that the elastic part and the shell are integrated.

In one embodiment, the edge of the cover plate forms a flange that is disposed around the body of the cover plate. The body comprises a first surface and a second surface which are oppositely arranged, and the first surface and the second surface are perpendicular to the light emitting direction of the touch screen. The flange extends into the mounting slot such that an edge of the first surface contacts a slot wall of the mounting slot. The touch screen is secured to the second surface.

In this embodiment, the edge of the first surface contacts the groove wall of the mounting groove, so that the cover plate is limited by the shell in the opposite direction of the light emitting direction of the touch screen, thereby preventing the cover plate from being separated from the shell and ensuring the reliability of the mobile terminal. When the cover plate is disassembled, the shell is deformed, the first surface is separated from the groove wall of the mounting groove, and the cover plate and the touch screen can be easily taken out.

It can be understood that the cover plate includes a display area and a non-display area surrounding the display area, and the housing covers part or all of the non-display area, so that the mobile terminal achieves a visual effect without a black edge or an approximate black edge.

Optionally, the flange is integrally formed with the body.

Optionally, in the light-emitting direction of the touch screen, the thickness of the flange is smaller than that of the body, so that the width of the mounting groove can be designed to be approximately the same as or the same as that of the body, and the width of the mounting groove can be set within a reasonable range to ensure the structural strength of the shell. Meanwhile, the flange is small in thickness, the elastic piece can be in contact with the first surface and the second surface at the same time, so that the flange can be wrapped well, the elastic force of the elastic piece can be fully applied to the cover plate, the connection relation between the cover plate and the shell is firm, and the reliability of the mobile terminal is guaranteed.

Further, the flange includes a root connecting the body and an end distal from the body. The root portion has a thickness greater than a thickness of the end portion. For example, the thickness of the flange decreases from the root portion to the end portion.

In this embodiment, since the thickness of the flange decreases from the root portion to the end portion, the user can easily remove the cover plate when the first surface is separated from the groove wall of the mounting groove.

Optionally, the housing includes a limiting portion, a part of a groove wall of the mounting groove is formed on the limiting portion, and the limiting portion contacts an edge of the first surface. At the moment, the limiting part has a limiting effect on the cover plate in the direction opposite to the light emitting direction of the touch screen. When the limiting part is subjected to an external force greater than a preset value, the limiting part is elastically deformed, and the preset value is greater than the elasticity for fixing the cover plate.

Specifically, the housing further comprises a main body part, and the limiting part is fixedly connected with the main body part. A part of the groove wall of the mounting groove is formed on the limiting part, and another part of the groove wall of the mounting groove is formed on the main body part, that is, the limiting part and the main body part together form the mounting groove.

In this embodiment, when the mobile terminal is in normal use, the limiting portion is hardly subjected to external force or is only subjected to external force smaller than the elastic force for fixing the cover plate, the limiting portion does not deform, and the cover plate can be well fixed by the limiting portion. When the cover plate and the touch screen need to be detached, a user applies an external force larger than the preset value to the limiting part to enable the limiting part to deform, the first surface of the cover plate is separated from the limiting part, and therefore the cover plate and the touch screen can be easily taken out.

The main body part and the limiting part are integrally formed so as to increase the structural reliability of the shell.

Optionally, the limiting portion is made of a plastic material, so that the limiting portion can deform under a large acting force, and the weight of the mobile terminal can be reduced.

Or, the spacing portion adopts metal material, makes the spacing portion can take place deformation and intensity is higher under great effort, makes the casing both has the metal feel outward appearance, has improved user experience, simultaneously spacing portion can protect better the apron.

Furthermore, the orientation of the limiting part is inclined towards the end face of the accommodating cavity, and a transition arc face is formed between the end face of the limiting part and the groove wall of the mounting groove. In the light emitting direction of the touch screen, the end face of the limiting portion forms a flared opening, so that the cover plate and the mobile terminal can easily slide over the end face of the limiting portion to be accommodated in the accommodating cavity. Simultaneously, the transition cambered surface can be convenient the apron with mobile terminal certainly accept the chamber and take out.

In one embodiment, an edge of the second surface contacts a wall of the mounting slot. At the moment, the shell has a limiting effect on the cover plate in the direction opposite to the light emitting direction of the touch screen. Different areas of the groove wall of the mounting groove are respectively in contact with the first surface and the second surface, so that the cover plate is better fixed in the light emitting direction of the touch screen, and the reliability of the mobile terminal is improved.

Of course, in other embodiments, the second surface does not contact the slot wall of the mounting slot. At this moment, the accommodating cavity has a larger volume, so that the non-display area of the touch screen can be shielded by the shell more fully, the visual frameless effect of the mobile terminal is realized, and the user experience is improved.

In one embodiment, the flange includes an upper surface that is a bevel extending from an end of the flange to the first surface and a lower surface that is a bevel extending from an end of the flange to the second surface. The end portion is connected between the upper surface and the lower surface.

In this embodiment, the upper surface is a slope extending from the end of the flange to the first surface, which facilitates the flange to leave the mounting groove and slide over the limiting portion. The lower surface is provided with an inclined plane extending from the end part of the flange to the second surface, and the flange can slide through the limiting part and stretch into the mounting groove.

In one embodiment, the elastic member includes a first elastic portion, a second elastic portion, and a third elastic portion connected between the first elastic portion and the second elastic portion. The first elastic part is pressed between the groove wall of the mounting groove and the upper surface, the second elastic part is pressed between the groove wall of the mounting groove and the lower surface, and the third elastic part is pressed between the groove wall of the mounting groove and the end of the flange.

In this embodiment, the elastic member is pressed to generate an elastic force: the first elastic part generates a first elastic force on the upper surface, the first elastic force is perpendicular to the upper surface and has a horizontal component force towards the center of the cover plate and a vertical component force opposite to the light emitting direction of the touch screen; the second elastic part generates second elastic force on the lower surface, the second elastic force is perpendicular to the lower surface and has a horizontal component force towards the center of the cover plate and a vertical component force in the same direction as the light emergent direction of the touch screen; the third elastic part generates a third elastic force against an end of the flange, the third elastic force being toward the center of the cover plate. The first elastic force, the second elastic force and the third elastic force are mutually matched, so that the cover plate is fixed.

Optionally, the upper surface and the lower surface are symmetrically arranged, and the first elastic portion and the second elastic portion are symmetrically arranged. In this embodiment, the first elastic portion and the second elastic portion are compressed to the same extent. The vertical component force of the first elastic force and the vertical component force of the second elastic force are the same in size and opposite in direction, so that the cover plate is subjected to a balancing force in the light emitting direction of the touch screen, and the matching structure of the cover plate and the shell is stable and reliable. The upper surface and the lower surface are symmetrically arranged, so that the processing difficulty of the cover plate can be reduced. The first elastic part and the second elastic part are symmetrically arranged, so that the processing difficulty of the elastic piece can be reduced.

It will be appreciated that the first resilient portion is compressed between the stop portion and the upper surface. When the limiting portion receives an external force larger than the preset value, the limiting portion deforms, the compressed portion of the first elastic portion is released, the first elastic force becomes smaller or disappears, the vertical component force of the second elastic force is larger than the vertical component force of the first elastic force, the cover plate obtains a resultant force along the light emitting direction of the touch screen, and therefore the elastic piece can assist a user in taking out the cover plate and the touch screen, and the difficulty in detaching the cover plate and the touch screen is reduced.

Detailed Description

The embodiments of the present application will be described below with reference to the drawings.

Referring to fig. 1 to 4 together, an embodiment of the present application provides a mobile terminal 100. The mobile terminal 100 may be a mobile phone, a tablet computer, a notebook computer, etc.

The mobile terminal 100 includes a housing 1, a cover plate 2, and an elastic member 4. The housing 1 has an accommodating cavity 11, and an installation groove 12 surrounding the accommodating cavity 11 is formed on a cavity wall 111 of the accommodating cavity 11. The elastic piece 4 is accommodated in the mounting groove 12. The edge of the cover plate 2 extends into the mounting groove 12 and presses the elastic member 4. When the edge of the cover plate 2 presses the elastic member 4, the elastic member 4 is elastically deformed (as shown in fig. 3, a dotted line indicates a shape of the elastic member 4 before being pressed, and a solid line indicates a shape of the elastic member 4 after being pressed). The cover plate 2 is fixed in the accommodating cavity 11 of the housing 1 through the elastic deformation of the elastic member 4.

The mobile terminal 100 further comprises the touch screen 3, and the touch screen 3 is contained in the containing cavity 11 and fixedly connected with the cover plate 2.

In this embodiment, the elastic member 4 of the mobile terminal 100 is elastically deformed to generate an elastic force for fixing the cover plate 2, so that the cover plate 2 is fixed to the housing 1, and the touch screen 3 fixed to the cover plate 2 is also fixed to the housing 1. When the cover plate 2 and the touch screen 3 are disassembled, the shell 1 deforms through large acting force, the elastic piece 4 is fixed, the elastic force of the cover plate 2 weakens or disappears, the edge of the cover plate 2 leaves the mounting groove 12, and the cover plate 2 and the touch screen 3 leave the shell 1, so that the disassembly is completed. Because casing 1 passes through elasticity chucking that elastic component 4 produced is fixed apron 2, apron 2 with realize dismantling the connection between the elastic component 4, apron 2 with there is not adhesion between the elastic component 4, consequently dismantles apron 2 with the degree of difficulty of touch-sensitive screen 3 is less, can not harm touch-sensitive screen 3 during the dismantlement for touch-sensitive screen 3 after the dismantlement can used repeatedly, thereby avoids causing huge material waste in mobile terminal 100's production and the maintenance process, practices thrift the cost.

Since the elastic member 4 is pressed between the mounting groove 12 and the cover plate 2, there is no gap between the housing 1 and the cover plate 2, and the mobile terminal 100 can achieve waterproof and dustproof. As the cover plate 2 is connected with the housing 1 through the elastic member 4 in the vertical direction of the light emitting direction X (as shown in fig. 2 and 3) of the touch screen 3, that is, in the display plane direction of the cover plate 2, the cover plate 2 is connected with the housing 1 through the hard-soft-hard connection, when the mobile terminal 100 is collided, the elastic member 4 can play a role in buffering, thereby reducing the risk of the cover plate 2 being broken. Since the bonding structure is eliminated between the cover plate 2 and the housing 1, the housing 1 does not need to be provided with a bonding surface for bonding the cover plate 2, so that the width of the black edge of the mobile terminal 100 can be reduced.

It can be understood that, in the vertical direction of the light emitting direction X of the touch screen 3, the edge of the cover plate 2 and the mounting groove 12 compress the elastic member 4 together, so the shape of the mounting groove 12 and the shape of the elastic member 4 are matched with the shape of the edge of the cover plate 2, and the mounting groove 12, the elastic member 4 and the cover plate 2 are matched more closely. For example, in a direction perpendicular to the light emitting direction X of the touch screen 3, the edge of the cover plate 2 is substantially rectangular, the mounting groove 12 is rectangular, and the elastic member 4 is also substantially rectangular.

Optionally, the housing 1 may be a middle frame of the mobile terminal 100, and forms a housing of the mobile terminal 100 after being matched with a rear cover of the mobile terminal 100. Alternatively, the housing 1 may be an integrally formed housing of the mobile terminal 100. Alternatively, the housing 1 is a front case of the mobile terminal 100, and forms an outer case of the mobile terminal 100 after being matched with a middle frame and a rear cover of the mobile terminal 100.

For example, as shown in fig. 2, the housing 1 is an integrally formed housing of the mobile terminal 100. The housing cavity 11 formed by the housing 1 is used for housing various components of the mobile terminal 100. The housing 1 forms an opening 13, and the housing chamber 11 is communicated to the outside of the housing 1 through the opening 13. A positioning step 112 surrounding the accommodating cavity 11 is further formed on the cavity wall 111 of the accommodating cavity 11, and the positioning step 112 is disposed toward the opening 13. The mobile terminal 100 further includes a middle plate 5, wherein the middle plate 5 is received in the receiving cavity 11 and contacts the positioning step 112. The middle plate 5 may be used to carry the touch screen 3. The space between the middle plate 5 and the housing 1 may be used to house a battery 6.

Optionally, the touch screen 3 is an In-cell touch screen (which refers to a structure In which a touch panel function is embedded In a liquid crystal pixel) or an On-cell touch screen (which refers to a structure In which a touch panel function is embedded between a color filter substrate and a polarizing plate). Of course, in other embodiments, the touch screen 3 may also adopt an external touch screen, that is, a touch panel and a display panel are stacked, the touch panel is disposed between the cover plate 2 and the display panel, and a touch circuit layer (a circuit layer for sensing a gesture action of a user) of the touch panel may be formed on the cover plate 2, so that the touch panel and the cover plate 2 form an integrated structure.

As an alternative embodiment, the elastic member 4 is made of a material having elasticity and no adhesive force. For example, the elastic member 4 is made of an elastic resin material or a silicone material. At this time, the elastic member 4 may generate the elastic force for fixing the cover plate 2, and meanwhile, no adhesive force is generated between the elastic member 4 and the cover plate 2, thereby facilitating the installation and detachment of the cover plate 2 and the touch screen 3.

As an alternative embodiment, the elastic member 4 is a one-piece structure with the housing 1. The elastic member 4 is fixed to the groove wall 121 of the mounting groove 12, and is non-detachably connected to the groove wall, so that the elastic member 4 does not displace during the mounting and dismounting processes of the cover plate 2, and the assembly efficiency and reliability of the mobile terminal 100 are improved.

In one embodiment, the elastic member 4 is directly formed on the groove wall 121 of the mounting groove 12 by injection molding, so that the elastic member 4 and the housing 1 are integrally formed and firmly connected.

In another embodiment, the elastic member 4 is bonded to the groove wall 121 of the mounting groove 12 by an adhesive, so as to realize an integral structure of the elastic member 4 and the housing 1.

As an alternative embodiment, referring to fig. 3 to 6, a flange 21 is formed on the edge of the cover plate 2, and the flange 21 is disposed around the body 22 of the cover plate 2. The body 22 includes a first surface 221 and a second surface 222 disposed opposite to each other, and the first surface 221 and the second surface 222 are perpendicular to the light emitting direction X of the touch screen 3. The flange 21 extends into the mounting groove 12 such that the edge of the first surface 221 contacts the groove wall 121 of the mounting groove 12. The touch screen 3 is fixed to the second surface 222.

In this embodiment, the edge of the first surface 221 contacts the groove wall 121 of the mounting groove 12, so that the housing 1 has a limiting effect on the cover plate 2 in the direction opposite to the light emitting direction X of the touch screen 3, thereby preventing the cover plate 2 from being separated from the housing 1, and ensuring the reliability of the mobile terminal 100. When the cover plate 2 is detached, the housing 1 is deformed, and the first surface 221 is separated from the groove wall 121 of the mounting groove 12, so that the cover plate 2 and the touch screen 3 can be easily taken out.

It can be understood that the cover plate 2 includes a display area and a non-display area surrounding the display area, and the housing 1 shields a part of or all of the non-display area, so that the mobile terminal 100 has a visual effect without a black edge or a nearly black edge.

Optionally, the flange 21 is integrally formed with the body 22. The cover 2 is a transparent hard plate, so that internal parts (e.g., the touch screen 3) of the mobile terminal 100 can be well protected, and a good light transmission effect can be achieved. The cover plate 2 may be a glass cover plate.

Optionally, in the light emitting direction X of the touch screen 3, the thickness of the flange 21 is smaller than that of the body 22, so that the width of the mounting groove 12 can be designed to be substantially the same as or the same as that of the body 22, and the width of the mounting groove 12 can be set within a reasonable range to ensure the structural strength of the housing 1. Meanwhile, since the thickness of the flange 21 is small, the elastic member 4 can contact the first surface 221 and the second surface 222 at the same time, so that the flange 21 can be wrapped well, the elastic force of the elastic member 4 can be sufficiently applied to the cover plate 2, the connection relationship between the cover plate 2 and the housing 1 is firm, and the reliability of the mobile terminal 100 is ensured.

Further, the flange 21 includes a root 211 connecting the body 22 and an end 212 remote from the body 22. The thickness of the root portion 211 is greater than the thickness of the end portion 212. For example, the thickness of the flange 21 decreases from the root portion 211 to the end portion 212.

In this embodiment, since the thickness of the flange 21 decreases from the root 211 to the end 212, the user can easily remove the cover plate 2 after the first surface 221 is separated from the groove wall 121 of the mounting groove 12.

Optionally, the housing 1 includes a position-limiting portion 14, a portion of the groove wall 121 of the mounting groove 12 is formed on the position-limiting portion 14, and the position-limiting portion 14 contacts an edge of the first surface 221. At this time, the limiting portion 14 has a limiting effect on the cover plate 2 in a direction opposite to the light emitting direction X of the touch screen 3. The position-limiting portion 14 is elastically deformed when an external force greater than a predetermined value is applied thereto, and the predetermined value is greater than the elastic force for fixing the cover plate 2.

Specifically, the housing 1 further includes a main body portion 15, and the stopper portion 14 is fixedly connected to the main body portion 15. A part of the groove wall 121 of the mounting groove 12 is formed on the stopper portion 14, and another part of the groove wall 121 of the mounting groove 12 is formed on the main body portion 15, that is, the stopper portion 14 and the main body portion 15 together form the mounting groove 12.

In this embodiment, when the mobile terminal 100 is in normal use, the position-limiting portion 14 is hardly affected by an external force or only an external force smaller than the elastic force for fixing the cover plate 2, the position-limiting portion 14 does not deform, and the position-limiting portion 14 can fix the cover plate 2 well. When the cover plate 2 and the touch screen 3 need to be detached, a user applies an external force greater than the preset value to the limiting part 14 to deform the limiting part 14, so that the first surface 221 of the cover plate 2 is separated from the limiting part 14, and the cover plate 2 and the touch screen 3 can be easily taken out.

It can be understood that the preset value is smaller than the elastic limit of the position-limiting portion 14, so that the position-limiting portion 14 is elastically deformed but not plastically deformed by an external force greater than the preset value, thereby reducing the risk of damage to the position-limiting portion 14 due to an excessive external force.

The mobile terminal 100 may set the material of the stopper portion 14 and the material of the main body portion 15 to be the same, thereby simplifying the manufacturing process of the housing 1 and reducing the cost of the housing 1. The mobile terminal 100 may also set the material of the position limiting portion 14 to be different from the material of the main body portion 15, so that the position limiting portion 14 and the main body portion 15 can better satisfy their respective roles. The material of the elastic portion 14 is more easily elastically deformed than the material of the main body portion 15.

The main body 15 and the stopper 14 are integrally formed to increase the structural reliability of the housing 1.

In one embodiment, the position-limiting portion 14 is made of a plastic material, so that the position-limiting portion 14 can deform under a large acting force, and the weight of the mobile terminal 100 can be reduced.

In another embodiment, the limiting portion 14 is made of a metal material, so that the limiting portion 14 can deform under a large acting force and has high strength, the housing 1 has a metal appearance, user experience is improved, and the cover plate can be better protected by the limiting portion 14.

Furthermore, an end surface 141 of the limiting portion 14 facing the accommodating cavity 11 is disposed in an inclined manner, and a transition arc surface 142 is formed between the end surface 141 of the limiting portion 14 and the groove wall 121 of the mounting groove 12. In the light emitting direction X of the touch screen 3, the end face 141 of the limiting portion 14 forms a flared opening, so that the cover plate 2 and the mobile terminal 100 can easily slide over the end face 141 of the limiting portion 14 to be accommodated in the accommodating cavity 11. Meanwhile, the transition arc surface 142 can facilitate the cover plate 2 and the mobile terminal 100 to be taken out from the accommodating cavity 11.

As an alternative embodiment, referring to FIGS. 7 and 8, the edge of the second surface 222 contacts the slot wall 121 of the mounting slot 12. At this time, in the opposite direction of the light emitting direction X of the touch screen 3, the housing 1 has a limiting effect on the cover plate 2. Different areas of the groove wall 121 of the mounting groove 12 respectively contact the first surface 221 and the second surface 222, so that the cover plate 2 is better fixed in the light emitting direction X of the touch screen 3, and the reliability of the mobile terminal 100 is improved.

Of course, in other embodiments, as shown in FIGS. 2-4, the second surface 222 does not contact the slot wall 121 of the mounting slot 12. At this time, the accommodating cavity 11 has a larger volume, so that the non-display area of the touch screen can be more sufficiently shielded by the housing 1, thereby realizing a frameless effect of the mobile terminal 100 in vision and improving user experience.

As an alternative embodiment, referring to fig. 3, 4 and 6, the flange 21 includes an upper surface 213 and a lower surface 214. The upper surface 213 is a slope extending from the end 212 of the flange 21 to the first surface 221, and the upper surface 213 is inclined with respect to the first surface 221. The lower surface 214 is a slope extending from the end 212 of the flange 21 to the second surface 222, and the lower surface 214 is inclined with respect to the second surface 222. The end portion 212 is connected between the upper surface 213 and the lower surface 214.

In this embodiment, the upper surface 213 is a slope extending from the end 212 of the flange 21 to the first surface 221, which facilitates the flange 21 to slide off the mounting groove 12 and over the limiting portion 14. The lower surface 214 is a slope extending from the end 212 of the flange 21 to the second surface 222, which facilitates the flange 21 to slide over the position-limiting portion 14 and extend into the mounting groove 12.

As an alternative embodiment, referring to fig. 3, 4, 6 and 9, the elastic element 4 includes a first elastic portion 41, a second elastic portion 42 and a third elastic portion 43 connected between the first elastic portion 41 and the second elastic portion 42. The first elastic part 41 is pressed between the groove wall 121 of the mounting groove 12 and the upper surface 213, the second elastic part 42 is pressed between the groove wall 121 of the mounting groove 12 and the lower surface 214, and the third elastic part 43 is pressed between the groove wall 121 of the mounting groove 12 and the end 212 of the flange 21.

In the present embodiment, the elastic member 4 is pressed (as shown in fig. 3, a dotted line indicates a shape of the elastic member 4 before being pressed, and a solid line indicates a shape of the elastic member 4 after being pressed) to generate an elastic force: the first elastic part 41 generates a first elastic force F1 to the upper surface 213, the first elastic force F1 is perpendicular to the upper surface 213, and has a horizontal component toward the center of the cover plate 2 and a vertical component opposite to the light emitting direction X of the touch screen 3; the second elastic part 42 generates a second elastic force F2 to the lower surface 214, the second elastic force F2 is perpendicular to the lower surface 214, and has a horizontal component toward the center of the cover 2 and a vertical component equal to the light emitting direction X of the touch screen 3; the third elastic part 43 generates a third elastic force F3 against the end 212 of the flange 21, the third elastic force F3 being toward the center of the cover plate 2. The first elastic force F1, the second elastic force F2 and the third elastic force F3 are engaged with each other, thereby fixing the cover plate 2.

Optionally, the upper surface 213 and the lower surface 214 are symmetrically disposed, and the first elastic portion 41 and the second elastic portion 42 are symmetrically disposed. In the present embodiment, the first elastic portion 41 and the second elastic portion 42 are compressed to the same extent. The vertical component of the first elastic force F1 is the same as the vertical component of the second elastic force F2, and the direction of the vertical component is opposite, so that the cover plate 2 is subjected to a balancing force in the light emitting direction X of the touch screen 3, and the matching structure of the cover plate 2 and the housing 1 is stable and reliable. The upper surface 213 and the lower surface 214 are symmetrically arranged, so that the processing difficulty of the cover plate 2 can be reduced. The first elastic portion 41 and the second elastic portion 42 are symmetrically disposed, so that the difficulty in processing the elastic member 4 can be reduced.

Of course, in other embodiments, the flange 21 and the elastic member 4 may be designed in other shapes, and the balance force of the cover plate 2 can be obtained by designing the compression amount of the elastic member 4 and the shape of the outer surface (e.g., the upper surface 213 and the lower surface 214) of the flange 21.

It is understood that the first elastic portion 41 is compressed between the stopper portion 14 and the upper surface 213. When the limiting part 14 is subjected to an external force larger than the preset value, the limiting part 14 deforms, the compressed part of the first elastic part 41 is released, the first elastic force F1 becomes smaller or disappears, the vertical component force of the second elastic force F2 is larger than the vertical component force of the first elastic force F1, and the cover plate 2 obtains a resultant force along the light emitting direction X of the touch screen 3, so that the elastic piece 4 can assist a user in taking out the cover plate 2 and the touch screen 3, and the difficulty in detaching the cover plate 2 and the touch screen 3 is reduced.

Alternatively, the upper surface 213 and the lower surface 214 may be connected by a flat surface or an arc surface. As shown in fig. 3 and fig. 6, if a planar connection is adopted, the plane is parallel to the light emitting direction X of the touch screen 3.

As an alternative embodiment, referring to fig. 3 to 5 and fig. 9, the groove wall 121 of the mounting groove 12 includes an upper wall 1211, a lower wall 1212, and a side wall 1213 connecting between the upper wall 1211 and the lower wall 1212. In this case, the mounting groove 12 is substantially U-shaped or square. The first elastic portion 41 is connected to the upper wall 1211, the second elastic portion 42 is connected to the lower wall 1212, and the third elastic portion 43 is connected to the side wall 1213.

The first surface 221 of the cover 2 is in contact with the upper wall 1211 without adhesive force therebetween, and the first surface and the upper wall are supported by each other through contact. The second surface 222 of the cover plate 2 is in contact with the lower wall 1212 without an adhesive force therebetween, and is supported by the contact.

In another embodiment, as shown in fig. 10, the mounting groove 12 may also be an arc-shaped groove.

It will be appreciated that the shape of the surface of the resilient member 4 that connects to the mounting groove 12 is adapted to the shape of the groove wall 121 of the mounting groove 12 to better connect the resilient member 4 to the mounting groove 12. For example, the mounting groove 12 is a U-shaped groove, and when the groove wall 121 of the mounting groove 12 is in a U-shaped profile, the surface of the elastic member 4 connected to the mounting groove 12 is also in a U-shaped profile. The mounting groove 12 is an arc-shaped groove, and when the groove wall 121 of the mounting groove 12 is arc-shaped, the surface of the elastic part 4 connected with the mounting groove 12 is also arc-shaped.

Referring to fig. 1 to fig. 10, an embodiment of the present invention further provides an assembling method of a mobile terminal, which can be used for assembling the mobile terminal 100 according to the above-mentioned embodiment.

The assembling method of the mobile terminal comprises the following steps:

step S01: providing a shell 1, wherein the shell 1 is provided with an accommodating cavity 11, and a mounting groove 12 arranged around the accommodating cavity 11 is formed on a cavity wall 111 of the accommodating cavity 11;

step S02: an elastic piece 4 is arranged in the mounting groove 12;

step S03: providing a touch screen assembly 7, wherein the touch screen assembly 7 comprises a cover plate 2 and a touch screen 3 fixedly connected with the cover plate 2;

step S04: and the touch screen assembly 7 is arranged in the accommodating cavity 11, so that the edge of the cover plate 2 extends into the mounting groove 12 and extrudes the elastic piece 4, and the cover plate 2 is fixed to the shell 1 through the elastic deformation of the elastic piece 4.

In this embodiment, in the assembly method of the mobile terminal, the elastic member 4 is first arranged in the mounting groove 12 of the housing 1 to form the touch screen assembly 7, and then the touch screen assembly 7 is directly mounted in the housing 1, so that the mounting process is simple and the difficulty is low, thereby reducing the assembly difficulty of the mobile terminal 100 and reducing the production cost of the mobile terminal 100.

It is understood that step S01 and step S03 are not limited to be in a sequential order, and may be performed simultaneously or in tandem. Step S02 is sequential to step S01. Step S04 follows step S01, step S02, and step S03.

In one embodiment, the disposing the elastic member 4 in the mounting groove 12 (step S02) specifically includes: the elastic member 4 is adhered to the groove wall 121 of the mounting groove 12 by a back adhesive.

In another embodiment, the disposing the elastic member 4 in the mounting groove 12 (step S02) specifically includes: the elastic member 4 is formed on the groove wall 121 of the mounting groove 12 by injection molding.

In this embodiment, the elastic member 4 and the housing 1 are of an integral structure and are firmly connected. It should be noted that in this step, the elastic member 4 needs to be cured at the same time, so that the surface of the elastic member 4 not connected to the housing 1 has no adhesive force, thereby avoiding the formation of an adhesive relationship between the elastic member 4 and the edge of the cover plate 2 in step S04.
